I think I have confused myself beyond belief or I am not comprehending this the right way, so I am reaching out to the experts for some help and guidance. The problem I am havnig is only some of the workstatins within my domain are an hour behind after daylight savings time (EST). I have done everything from 'net time' to see where the workstation is getting its time from, to trying registry changes on the servers and group policies to try and fix the problem. Some background, I have 4 DC's (Lets call them A, B, C, and D) in a child domain. I have no access to make any changes within the forrest, and the PDC of the forrest resides in the UK. Three of my DC's (A, B, C) including my domains PDC (A) look to the PDC of the forrest per the 'w32tm /monitor' command. My remaining DC (D) looks at the child domain PDC (A), I am not sure if this is right and the others are wrong, the time is right on this last DC (D). This is where I think the problem is, the workstations that are an hour behind, when I do a 'net time', they point to this DC (D), and give me this from any workstation and server including my domains PDC:
Current time at \\DomaniControllerD is 3/23/2011 12:55 PM
Local Time <GMT-4:00> at \\DomaniControllerD is 3/23/2011 1:55 PM
So basically how can I get my servers setup to sync time the proper way and then have this filter down to the workstations?
